Abstract: PURPOSE:To lessen the change in characteristics with the lapse of time and to obtain a stable performance by making the photoconductivity and dark conductivity of a semiconductor a specific ratio or below of the initial value of the photoconductivity and dark conductivity before receiving an external stimulus. CONSTITUTION:A light shielding film 8a for preventing the incidence of excess external light on optical switching elements 4a is embedded into a substrate 1a. The patterns of the light shielding film 8 are formed at the points overlapping on the patterns of the optical switching elements 4. Optical waveguides Yn are formed on the substrate 1a. Light emitting arrays are previously formed at the ends of these optical waveguides Yn, etc. Then, plural signal electrodes Xm are formed crossing the respective optical waveguides Yn, etc., on a clad layer 3. The light emitting elements are made to emit light and an external stimulus is applied to the semiconductors by subjecting the semiconductors to an aging treatment with photoirradiation, thereby, the photoconductivity and dark conductivity of the semiconductors are confined to be >=20% of the initial values of the photoconductivity and dark conductivity before receiving the external stimulus.
